Abstract: A line connector assembly and a line connector for fluidically connecting fluid lines is described. A housing has: a receiving space; a connecting piece; and a channel through which fluid can flow. The channel through which fluid can flow has a first straight channel portion and a curved channel portion. The curved channel portion directly adjoins the first straight channel portion in such a way that fluid can flow through, and the curved channel portion can be connected to a second straight channel portion in such a way that fluid can flow through. The curved channel portion has an inner channel line and an outer channel line, the outer channel being less strongly curved than the inner channel line. The outer channel line of the curved channel portion has, over an entire extent of the curved channel portion, a length (L).

Abstract: A valve coupling assembly has a first fluid line connector with a first fluid line and a second fluid line connector with a second fluid line. In an operational state, the first and second fluid line connector are engaged to each other and the first fluid line and the second fluid line are connected in fluid communication. In a disengaged state, the first fluid line connector and the second fluid line connector are disengaged from each other and the first and second fluid line are disconnected from each other. A first valve is arranged in the first fluid line, the first valve being configured to control a flow of a fluid in the first fluid line. In a closed state of the first valve, the first fluid line is sealed, and, in an open state of the first valve, the first fluid line is open. The second fluid line connector comprises at least one push element mounted to a body of the second fluid line connector.

Abstract: A jet pump comprising a jet nozzle for accelerating a propellant. The jet nozzle has a convergent inlet part and an outlet part connected to the convergent inlet part. The outlet comprises an inner wall diverging at an opening angle. The opening angle is designed such that a propellant flowing through the outlet part at subsonic speed is detached from the inner wall and a propellant flowing through the outlet part at supersonic speed is guided by the inner wall. An automatic, cost-effective and simple changeover of the jet pump to different pressure ratios is hence provided.
